Abstract

The invention relates to an electric locomotive cooling system, comprising liquid medium cooling loops for cooling a main converter, a main transformer and a water-cooled traction motor respectively, and a combined cooler; liquid tanks of the combined cooler are connected respectively with the corresponding liquid medium cooling loops, a heat-absorbing line of a compression refrigerator is in S-shaped round-strip distribution in the liquid tanks of the combined cooler and is soaked in the liquid cooling medium. The radiating efficiency of the main converter, main transformer and traction motor of an electric locomotive is greatly improved, a lot of axial-flow fans are omitted, equipment weight is reduced, less space is used, fan noise is avoided, there is no stain and solid flocculent accumulation outside the combined cooler, equipment false steps are decreased, and equipment maintenance cost is reduced.

Description

technical field [0001] The invention relates to a cooling system for an electric locomotive, belonging to the technical field of railway locomotives. Background technique [0002] In the prior art, the electric locomotive adopts forced ventilation to cool the traction motor. Usually, an axial flow fan is set corresponding to several traction motors on a bogie for forced ventilation. In order to enhance the cooling effect, there is also a scheme of setting an axial flow fan corresponding to each traction motor. For the cooling of the main converter and the main transformer, the cooling circuits of the main converter and the main transformer are connected to a composite cooler, and then the composite cooler is still forced to be ventilated by an axial flow fan. These solutions generally have many problems such as large space occupation, heavy equipment weight, high working noise, low heat dissipation efficiency, many equipment failures, and high maintenance costs.
